High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How does the Stellar Core history subsystem manage ledger archiving?▼

The Stellar Core history subsystem manages ledger archiving by utilizing buckets, history blocks, and checkpoints within a publication pipeline to store long-term historical data. It details key classes like HistoryManager and CheckpointBuilder.

What role do checkpoints play in the Stellar consensus protocol history?▼

Checkpoints in the Stellar consensus protocol history act as synchronized archival points built by the CheckpointBuilder. They ensure data consistency across distributed systems before being published to long-term history archives.

How does crash recovery work for the Stellar Core history subsystem?▼

Crash recovery in the Stellar Core history subsystem relies on specific threading models and checkpointing mechanisms. The system restores ledger archiving states by validating history blocks and buckets to maintain data integrity after failures.

What are the key classes in the Stellar Core history publication pipeline?▼

Key classes in the Stellar Core history publication pipeline include HistoryManager, CheckpointBuilder, and HistoryArchiveManager. These components coordinate the creation and publication of history blocks to distributed system archives.

When do I need to understand Stellar Core buckets and history blocks?▼

You need to understand Stellar Core buckets and history blocks when developing or maintaining the consensus protocol's ledger archiving functionality. These components form the foundational storage mechanisms for the history subsystem's data flows.
